Police Commissioner Richard Ross said the attacker claimed
to have been inspired by the Islamic State terror group,
also known as ISIS. Ross said the targeted officer was shot three
times and that it was something of a miracle that he survived
such a direct attack.

"I don't know how this officer survived," Ross said.

The alleged attacker was identified as Edward
Archer.

The still images appear to show him approaching a
police-car window as he fired his gun, and then hurrying away.
